Kenalog and antihistimines

I had been suffering from severe allergies for about 10 years and had been through the desensitizing shots, antihistimines, and whatever else one can imagine. I was a human dartboard for some of the allergists I consulted. Finally, this past Spring, my GP suggested that I try a Kenalog shot. At first I declined because I knew there could be complications with taking corticosteriods. After a month or two of suffering with the allergies and my fibromyalgia in full swing, I decided to get the shot. The difference in the allergies was like night and day. And the bonus to the treatment was that my fibromyalgia was decreased and a pressure buildup in my left ear subsided. Yes, I experienced longer and heavy periods, and occasional acne (which I was able to control with topicals), and I'm certain if I made the effort I could attribute other oddities in my life to the shot. However, I have been miserable lately since I believe the shot is wearing off. After reading all the horror stories on this site it has made me wary of the use of Kenalog. But we must remember that not all humans react the same way to all med.
